Question

Which description correctly summarizes how an electric motor causes an axle to turn?
O Force generated through the brushes rotates the commutators. They then generate a force that rotates the
armature to spin until the like poles of the electromagnet and the permanent magnet align and motion stops.
O The poles of the magnetic field generated around the armature are attracted to the opposite poles of the
permanent magnet. As the opposite poles align, the commutator reverses the current direction so like poles are
aligned and the armature continues to spin.
O The poles of the magnetic field generated around the armature are attracted to the like poles of the permanent
magnet. This causes the armature to spin and the electricity within the armature to flow back through the circuit
to the battery

Answer 1

Answer:

B. The poles of the magnetic field generated around the armature are attracted to the opposite poles of the permanent magnet. As the opposite poles align, the commutator reverses the current direction so like poles are aligned and the armature continues to spin.

Explanation:

hope i helped, its correct on EDGE2021

Answer 2

The poles of the magnetic field generated around the armature are attracted to the opposite poles of the permanent magnet. As the opposite poles align, the commutator reverses the current direction so like poles are aligned and the armature continues to spin.

The answer is option B.

What is a magnetic field in simple terms?

The definition of a magnetic area is an area in the area near a magnet or an electric-powered modern-day in which a physical discipline is comprised of a transferring electric fee that creates pressure on any other transferring electric price. An example of a magnetic field is the Earth's magnetic field.

All magnets have north and south poles. Opposite poles are interested in each other, at the same time as the same poles repel each other. Whilst you rub a chunk of iron along a magnet, the north-seeking poles of the atoms in the iron line up in an equal course. The force generated by means of the aligned atoms creates a magnetic field.
